Figure 3From: Identification and functional characterization of bidirectional gene pairs and their intergenic regions in maizeIdentification of BD PROs from the MA and RS data sets. Embryos were isolated from 20 DAP immature maize kernels. Each construct was introduced twice using a particle gun with six embryos per bombardment. A: Promoters cloned based on the microarray data set (MA); B: Promoters cloned based on the RNA-seq data set (RS). Putative BD PROs that showed promoter activity in both directions are indicated by a red box. The remaining putative BD PROs showed either promoter activity in one direction or no promoter activity.Back to article page
